Similar thing happened to Burger King in India. Although they still get to keep using the name I guess.

I am in a similar situation, the only difference is that I have played with things like networking, docker etc before at work. Honestly 10k INR is not enough in my opinion. You can get refurbished hardware which will be very old, consume more electricity and will not be good performance wise. You will either have to increase your budget or compromise severely on the specs.
